Abstract (en)
[origin: EP0123340A1] 1. Circuit for measuring the background-noise characteristics represented at the input of an electronic component, including an electric power supply (2) with a DC bias with respect to a DC voltage reference (R), a load impedance (4) connected to said power supply and to a first terminal (5) which in turn is connected to the component output, an amplifier (6) with an input connected to the first terminal (5) above and an output connecting to means (18) measuring the characteristics of the signal output from said amplifier, and a source impedance (10) connected to a second terminal (11) in turn connected to the component input, said measuring circuit being characterized in that the output of the amplifier (6) is fed through a voltage divider (12) to the source impedance (10), where said voltage divider has an upper terminal (12a) connected to said amplifier output, a center terminal (12b) connected to the source impedance (10) and a lower terminal (12c) connected to the DC voltage reference (R).
